Maybe things will improve this fall as it seems to me that there is an advantage price wise to booking several months in advance. Last minute deals are fine for one week get aways but that is not what I have in mind. Cost is crucial for us as is the weather. It has to be more than the touted "spring like" weather you see for so many places. Here it is mid July in Alberta and we are still getting spring like weather with highs of 15! Hardly what I am looking for in the middle of winter.
I am reading El Nino is going to be impacting Central and South America this winter..... increased rain, winds and abnormal temperatures may make things a bit dicey to figure out. Historically some of these countries have not fared very well with a lack of infrastructure and means to cope with mud slides and water problems and the like.
Well, I will just keep on looking.....
